By way of example, in the case of bulk shipments, approximately 36 per cent in transportation costs could be saved, as freight costs are on the order of $15.50 per metric ton, whereas that figure could be reduced to approximately $10 per metric ton if vessels could take cargoes back to the United States.
Actualmente se realizan erogaciones del orden de 15,50 dólares por tonelada métrica por concepto de flete, cuando la cifra pudiera reducirse a aproximadamente unos 10,00 dólares, si los barcos pudieran tomar cargas de retorno hacia los Estados Unidos.
